Overview
Polyphase Energy Metering IC with Pulse Outputs and Anti-Tamper Features SA4301A ICDC - a division of FEATURES 1 Meets the IEC62053, CBIP-88 and IS137799-1999 specification requirements for Class 1 AC static watthour meters for active energy 1 Motor drive outputs (MOP, MON) provide average active power information and can drive an electromechanical counter or an impulse counter directly 1 LED pulse output for calibration purposes supplies average active power information 1 Configurable for different meter ratings 1 Per phase energy direction indication 1 Per phase missing phase indication 1 Phase sequence error indication 1 Precision on-chip oscillator (70ppm/°C drift) 1 Precision on-chip voltage reference (10ppm/°C drift) 1 On-chip anti-creep function (0.
005% of EMAX) 1 Low power consumption (<40mW typical) 1 Measures AC inputs only DESCRIPTION The SAMES SA4301A is an accurate polyphase power/energy metering integrated circuit providing a single chip solution for three phase energy meters.
Very few external components are required and the chip includes a direct drive capability for electro-mechanical counters.
The SA4301A does not require an external crystal or voltage reference.
A precision oscillator and a precision voltage reference to supply the circuitry with a stable frequency and stable reference currents are integrated on the chip.
The SA4301A metering integrated circuit generates a pulse output, the frequency of which is proportional to the active power consumption.
Programmable inputs allow the meter manufacturer to configure the SA4301A for different meter maximum currents (IMAX) and nominal voltages (VNOM) without having to change the stepper motor counter or impulse counter gear ratio.
The LED pulse output follows the average active power consumption measured and is intended for meter calibration purposes.
In fast calibration mode this output provides a high frequency pulse rate following the average active power consumption and can be used for f...
